After checking /var/log/messages I see the following record to be repeated every one minute: Apr 2 08:19:40 servername db_name: Access denied for user 'xxxx'@'localhost' (using password: YES)
I used to host a clients website under that db name but not anymore because he had put up a torrent tracker so I asked him to move out. Months later it seems that I m still getting requests.
I checked mysql and there is no fb under that name anymore so I cant understand where this message comes from.
